Full O(α) corrections to e+e-→f∼if∼¯j
Abstract
We present a complete precision analysis of the sfermion pair production process e+e-→ ftilde i ftilde ¯j(f=t,b,τ,ντ) in the minimal supersymmetric standard model. Our results extend the previously calculated weak corrections by including all one-loop corrections together with higher order QED corrections. We present the details of the analytical calculation and discuss the renormalization scheme. The numerical analysis shows the results for total cross sections, forward-backward, and left-right asymmetries. It is based on the SPS1a' point from the SPA project. The complete corrections are about 10% and have to be taken into account in a high precision analysis.
